OpenAI Raises $40B at $300B Valuation in SoftBank-Led Round

March 31, 2025

Details

  • OpenAI has raised $40 billion in fresh funding, bringing its valuation to $300 billion in what stands as the largest private tech fundraising to date.
  • The round was led by SoftBank, with significant participation from Microsoft, Coatue, Altimeter Capital, and Thrive Capital.
  • The funds are earmarked for advancing artificial general intelligence research, scaling infrastructure, and powering the Stargate project, OpenAI’s major new AI-Oracle cloud partnership.
  • This funding more than doubles OpenAI’s valuation from its October 2024 round and surpasses previous records such as Ant Group’s 2018 $14 billion raise.
  • OpenAI now serves 500 million weekly ChatGPT users and anticipates its annual revenue will triple to $12.7 billion in 2025.

Impact

This massive capital injection reinforces OpenAI’s leadership as generative AI transforms a trillion-dollar market, but also highlights the growing pressure to finalize its shift to a for-profit structure by year’s end. The company’s momentum comes amid fierce competition from Google and Anthropic, with its Stargate initiative promising to further influence the economics of AI infrastructure.
